The data was analyzed using Wolfram’s theory of classification of grammatical features of AAVE in Ramengvrl’s songs to elaborate on the purpose of its use. The data analyzed were qualitatively collected by closely and thoroughly listening to the songs and reading the transcribed lyrics. The results are as follows: Ramengvrl employs 8 out of 13 grammatical features of AAVE. Those are copula/auxiliary absence, specialized auxiliary, subject-verb agreement, negation, remote “been,” nominals, non-standard pronouns, and question formation.
